The surgery was performed by Philadelphia-based specialist William Meyers.

In a statement Thursday afternoon, the Vikings confirmed Meyers "was able to successfully repair Adrian's adductor muscle while also doing a compartmental release" in the surgery at the Vincera Institute.

Peterson is expected to make a full recovery in approximately six weeks, the team said.

The adductor release is minimally invasive and cuts an irritated tendon. Meyers also performed Peterson's sports hernia surgery after last season.

Peterson, 28, missed two of the Vikings' last three games because of the groin as well as a foot injury and dropped out of the Pro Bowl last week.

The groin was an issue since at least mid-November, most notably hobbling Peterson in a Nov. 17 loss at Seattle. He finished the season with 1,266 rushing yards in 14 games, one year after winning the MVP and rushing for 2,097.

Peterson has four years and $57 million in non-guaranteed salary and bonuses remaining on the contract extension he signed in September 2011. His scheduled compensation for 2014 in $12 million.
